Corpus annotation has become a major force in computational
linguistics. New annotation often leads to new task definitions and
new standards of analysis. Through the creation of new answer keys and
training data, annotation often leads the field in new directions. The
first "Frontiers in Corpus Annotation" workshop (at HLT-NAACL 2004)
focused on descriptions of cutting edge projects in corpus annotation,
some of which may help define the future of the field.  At last year's
workshop, we also compared assumptions underlying different annotation
projects in light of both multilingual applications and the pursuit of
merged representations that incorporate the result of various
annotation projects.

Over the past few months, researchers representing several different
sites and annotation efforts have been working on a unified semantic
representation of two sentences, which attempts to go beyond what is
currently practical to annotate. The annotation includes argument
structure for all categories (not just verbs and nouns), discourse,
coreference, time, ontological information, etc. We are trying to
prepare a pie-in-the-sky goal for future annotation. ("Pie in the Sky"
is an idiomatic expression that means ideal, but not necessarily
practical.)  The ultimate target annotation would provide as complete
a semantics as possible and would be language neutral to the extent
possible (while still being anchored to the actual data).  Potential
workshop participants are encouraged to view the "Pie in the Sky" data
and current analysis, which is to be found on the "Pie in the Sky"
website.

The organizers of this workshop will select papers that describe
attempts to advance the level of linguistic content in corpus
annotation and/or the inventory of languages covered in corpus
annotation. We are interested in all papers on these topics. However,
we expect to have a substantial number of papers related to the
pie-in-the-sky project. Pie-in-the-sky papers typically would discuss
annotation that has been or should be incorporated into the
pie-in-the-sky annotation, issues of translation of the analysis and
the example to other languages, as well as alternative analyses of the
data. Issues of learnability, comparisons with other annotation or
knowledge representation schemes, critiques based on additional data,
etc. are also relevant.  In discussing alternative analyses, we
encourage authors to focus on actual differences of analysis and
avoiding discussion of differences in data structure. Toward this
end, the "Pie in the Sky" website includes a full Feature
Structure representing the current analysis, as well as a Dependency
Structure that represents most salient features.

annotated corpora and new types of corpus annotation. This includes
annotators, lexicographers, system developers and those designing
future NLP system evaluation tasks for the NLP community.

FORMAT FOR SUBMISSION: Submissions should not exceed 8 pages in
length. Format requirements will be the same as for full papers of ACL
2005, except that submission will not be blind. See

to corpusws@cs.nyu.edu. The paper should be
an attachment in PDF format and the heading on the
email should read "PAPER SUBMISSION". Notification of
acceptance or rejection will be sent to the originating
email address.
